摘要： Embodiments of a method for producing bio-oil include hydrothermal liquefaction of a biomass (e.g., a lignocellulosic biomass) feedstock to provide a process stream comprising crude oil and an aqueous fraction. The process stream is catalytically upgraded by contact with a sulfided-ruthenium catalyst, in the absence of added hydrogen, at a temperature and pressure effective to reduce an oxygen content of the crude oil, reduce a nitrogen content of the crude oil, reduce a total acid number of the crude oil, increase a H:C mole ratio of the crude oil, reduce a density of the crude oil, reduce a moisture content of the crude oil, reduce viscosity of the crude oil, or any combination thereof, thereby producing an upgraded oil and an upgraded aqueous fraction, which are subsequently separated. The catalytic upgrading process may be a plug-flow process and/or may be performed at or near liquefaction conditions.

摘要： A combined hydrothermal liquefaction (HTL) and catalytic hydrothermal gasification (CHG) system and process are described that convert various biomass-containing sources into separable bio-oils and aqueous effluents that contain residual organics. Bio-oils may be converted to useful bio-based fuels and other chemical feedstocks. Residual organics in HTL aqueous effluents may be gasified and converted into medium-BTU product gases and directly used for process heating or to provide energy.

摘要： A hydrothermal liquefaction (HTL) system can comprise a biomass slurry source, a first pump in fluid communication with the slurry source and configured to pressurize a biomass slurry stream from the slurry source to a first pressure, a first heat exchanger in fluid communication with the first pump and configured to heat a slurry stream received from the first pump to a first temperature, a second pump in fluid communication with the first heat exchanger and configured to pressurize a slurry stream received from the first heat exchanger to a second pressure higher than the first pressure, a second heat exchanger in fluid communication with the second pump and configured to heat a slurry stream received from the second pump to a second temperature higher than the first temperature, and a HTL reactor configured to produce biocrude from a slurry stream received from the second heat exchanger.

摘要： A system and process are described for clean separation of biocrudes and water by-products from hydrothermal liquefaction (HTL) product mixtures of organic and biomass-containing feedstocks at elevated temperatures and pressures. Inorganic compound solids are removed prior to separation of biocrude and water by-product fractions to minimize formation of emulsions that impede separation. Separation may be performed at higher temperatures that reduce heat loss and need to cool product mixtures to ambient. The present invention thus achieves separation efficiencies not achieved in conventional HTL processing.
